Well. Don't buy a used car from Pennsylvania. They like rust.
I have a few spots of rust that are really tiny, and one spot where I would like to treat it ASAP, it's beginning to bubble under the paint. Spots are on a door (corner), and the trunk (lip edge).
Any suggestions?!? I'm sure there have been posts about this before, but I'm doing this not just for me, but for those out there who would like a nice clean and clear answer for Rust right there on the top o the page.
The car is a titanium silver color, but that shouldn't matter becaus eI can vinmatch and get the touch up paint from the dealer.
Anyway... any tips/hints/tricks?

I've got the same bubbling on the rear wheel arch and on the lip of the windscreen which is a real arse of a place to get it. Gonna cost alot to get the screen taken out and have it seen too.

Theres no quick way around it unfortunately, you're going to have to take it into a shop and have them treat the skin of the metal, then respray it. Get it done NOW though otherwise a year down the road you could be looking at a whole new panel.

I live in Ohio (they throw piles of salt here ). I had 2 rust spot on the bottom of two doors (about 1 inch long and 1/4 inch wide each) on my 98 328i that I fixed myself. More rust is starting to appear at the edge of te trunk lid and another door, and I'll take care of it, sometime soon ghead
